COAL-OIL BURNER.

kpplication'file'dlvlarch 10,1927. 'Seria1No.174,166.

M'y invention relates to improvements in coal oil heaters and itconsists in the combinations, constructions, and arrangementshereinafter described and claimed.

An object of my invention is to provide a coal oil heater which providescentrally disposed means for moving the wick, whereby uniform pressureis applied at all points around the circular wick for raising orlowering the same, thus preventing binding.

A further object of my invent-i on is to provide a device of the typedescribed in which novel means is provided for preventing the top edgeof the wick from burning. This construction prevents part of the edge ofthe wick from burning more rapidly than other parts of the wick, thisburning normallybeing caused by an, unevenly cut wick. It will thereforebe seen that the wick will burn uniformly over its entire exposed areaand will therefore give off a uniform flame.

Other objects and advantages will appear in the followingspecifications, and the novel features of the invention will beparticularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a partof this application in which the figure shows a vertical section throughthe device.

In carrying out my invention I provide a chimney 4 which is supported bya casing 3 which in turn is supported by legs 2. The casing 3 has aninwardly extending bead 1 which carries an oil fount 5. V

I will first describe the means for raising and lowering the wick 6. Theoil fountv 5 has an air pipe 7 therein, this being centrally disposedand housing the working mechanism hereinafter described. A radiallyextending tube 8 extends through the oil fount 5 and houses acylindrical casing 9. The casing 9 is frictionally held in the tube 8.\Vithin the casing 9 I mount a shaft 10 which is journalled in the ends11 and 12 of the casing 9. The inner end of the shaft 10 carries thepinions 13 while the outer end carries an actuating wheel 14c.

A perforated rack bar 15 is provided with arms 16 which have trunnions17 slidably mounted in slots 18. The trunnions 17 extend into a wickcarrying cylinder 19 to raise the wick 6 when the wheel 14: is actuated.

A burner cap 20 is slidably mounted upon a rod 21 and carries a flange22 which has a downwardly bent portion 23 partially covering the upperedge of the wick 6. The portion 23 prevents the upper edge of the wick 6from burning.

A stop nut 24 is secured to the top of the rod 21 for limiting themovement of the burner cap 20. The lower end of the rod 21 is supportedby a cross bar 25 which in turn is secured to supporting members 26thathave L-shaped slots 27 therein for removably receiving pins .28 carriedby the air pipe 7. Y

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The chimney 4 is hinged tothe casing 3 in the usual mannerand is adapted to be swung back forpermitting the oil-fount 5 to be removed when necessary. A slot 29 isprovided for permitting the shaft 10 to be moved through the casing 3when the oil fount 5 is removed. The wheel 14: is disposed at asufficient distance above the floor for permitting the ready operationof the wheel. It will also be noted that there will be no binding actionbetween thecylinder 19 and the air pipe 7 when the cylinder is moved.This is true because the lifting force is centrally disposed withrespect to the cylinder 19. A uniform flame from wick 6 is assuredbecause the portion 23 of the flange 22 will cover any frayed edges ofthe wick'andthus prevent these frayed edges from burning.

I claim:

1. In an oil heater, an air pipe,a wick cylinder slidable thereon, awick mounted on the exterior of the cylinder so as to be substanti allyflushtherewith at the upper end;

.an axially movable member on the inside of engaging the air pipe tolimit the.upward movement of the burner cap said last means comprising across-bar attachable to the inside of the air pipe and an adjustable rodextending upward from the cross bar through the burnercap with means onsaid I rod for limiting the upward movement of the burner cap. e

I 3. An oil heater comprising in combination an. oil fount, an air pipeextending cen- 5 trally through said fount, a burner cap slidablymounted in said air pipe and means connected to the burner cap anddetachably engaging the air pipe to limit the upward movement of theburner cap; said limiting 10 means comprising a cross-bar with asupportr ing member having bayonet slotstherein,

rod extending through said cross-bar and through the burner cap, andhaving a stop device on the top of the rod to limit the upward movementof the burner when elevated by theupward movement of the Wick. v Intestimony whereof I aflix my signature.
